Found life on planet K2-18. Let's clarify

#Space #alienlife #planets
JWST has spotted dimethyl sulfide and dimethyl disulfide in the atmosphere of exoplanet K2‑18 b—gases on Earth linked almost exclusively to marine life. In this video we break down the evidence, the 3‑sigma caveats, and what upcoming JWST and ARIEL observations must show to confirm or refute the dream of a warm, life‑rich ocean 124 light‑years away.
